# from libtool manual:
# Here are a set of rules to help you update your library version information:
#   Start with version information of ‘0:0:0’ for each libtool library.
#   - Update the version information only immediately before a public
#   release of your software.
#   - If the library source code has changed at all since the last
#   update, then increment revision
#   - If any interfaces have been added, removed, or changed since the
#   last update, increment current, and set revision to 0.
#   - If any interfaces have been added since the last public release,
#   then increment age.
#   - If any interfaces have been removed since the last public release,
#   then set age to 0.
